firewalld operations that delete kube-proxy's iptables rules.

  As a side effect of these changes, kube-proxy's
  `sync_proxy_rules_last_timestamp_seconds` metric no longer behaves the
  way it used to; now it will only change when services or endpoints actually
  change, rather than reliably updating every 60 seconds (or whatever). If you

  - A server-side apply request that makes unrelated changes to an object which has duplicate items in a keyed list no longer fails, and leaves the existing duplicate items as-is.

* StatefulSet: The deprecated `pod.alpha.kubernetes.io/initialized` annotation for interrupting the StatefulSet Pod management is now ignored. StatefulSets with this annotation set to `true` or with no value will behave just as they did in previous versions. Dormant StatefulSets with the annotation set to `false` will become active after upgrading.

The shift operators implement arithmetic shifts if the left operand is a signed
integer and logical shifts if it is an unsigned integer.
There is no upper limit on the shift count. Shifts behave
as if the left operand is shifted <code>n</code> times by 1 for a shift
count of <code>n</code>.
As a result, <code>x &lt;&lt; 1</code> is the same as <code>x*2</code>
and <code>x &gt;&gt; 1</code> is the same as
